Fuzzy Logic Based Spectrum Sensing Technique for Cognitive Radio
A cognitive radio is a type of intelligent radio system. It automatically detects available spectrum in a given frequency band. It automatically and intelligently changes its parameters. These parameters include transmission and reception. Therefore, frequent wireless communication is achieved for a given frequency band at specific location. There are multiple techniques used to sense and avail...
متن کاملGame Theory Based Spectrum Sensing Technique Using Cognitive Radio Networks
In Cognitive Radio Networks, though energy detection technique is simple with short sensing time, its performance is poor under low Signal to Noise Ratio (SNR) conditions. Hence in this paper, we propose to design an optimized adaptive spectrum sensing technique Using Game Theory Model for Cognitive Radio Networks. Initially, the secondary users decide the sensing technique to be applied based ...
متن کاملEnergy Detection Technique for Spectrum Sensing in Cognitive Radio
With unprecedented growth of the subscribers in modern cellular and wireless data communications, there is an acute scarcity of additional bandwidth to meet the ever growing demand. To ease the constraint of additional bandwidth, utilization of the existing system has been a topic of recent interest. Cognitive Radio is a new technique in which the spectral holes in unutilized spectrum are deter...
متن کاملKurtosis based spectrum sensing in cognitive radio
In this paper, we consider spectrum sensing in cognitive radio networks based on higher order statistics. The kurtosis, a fourth order statistic, which is a measure of deviation from Gaussianity, is used as a detection statistic. An optimum threshold is set up based on the Neyman-Pearson criterion and analytical expression for upper bound on probability of miss is derived for a single pair of p...
متن کاملAn Adaptive Spectrum Sensing Model for Cognitive Radio Application
The problem of underutilization of spectrum may be solved by allowing the Secondary Users (SU) to use the spectrum allocated to the Primary Users(PU) (license holder of a spectrum band) when they are not using it, without causing any harmful interference to the PUs. Cognitive Radio (CR) technology promises to solve the problem of spectrum underutilization and spectrum crowding. The cognitive us...
